What are some examples of scope in Python?

In Python, scope refers to the visibility of variables. There are four types: local, enclosing, global, and built-in.

Can you give me an example of local scope?

Sure! In a function, variables defined inside are local to that function. For example:

def my_function():
    x = 10  # x is local to my_function
    print(x)
my_function()  # This will print 10

What about global scope?

Global scope means the variable is accessible throughout the entire program. For example:

y = 5  # y is global

def my_function():
    print(y)  # This will print 5
my_function()

Are there any examples of enclosing scope?

Yes! Enclosing scope occurs in nested functions. Here's an example:

def outer_function():
    z = 20  # z is in the enclosing scope
    def inner_function():
        print(z)
    inner_function()  # This will print 20
outer_function()
